DESIGN4-134 F-Head



This Kaiser-built engine is of a combination valve-in-head/valve-in-block configuration. The intake valves are located in the head; the exhaust valves, in the block. The head and block are cast iron. The crankshaft is supported by three main bearings.

6-225, 8-350

These Buick-built engines are of a 90º V, overhead valve configuration, with cast iron heads and block. The pistons are cast aluminum. The 6-225 crankshaft is supported by four main bearings; the 8-350 crankshaft is supported by five main bearings.

6-226 L-Head

This Kaiser-built engine is used in the FC-170 truck. It is of the valve-in-block, or flathead, design. The head and block are cast iron. With this arrangement, there are no moving parts in the cylinder head. The crankshaft is supported by four main bearings.

6-230

The overhead camshaft 6-230, built by the Continental Engine Corp. was a fairly radical design for its day, incorporating features found in more modern engines. The camshaft has only six cams, with the same cam operating both intake and exhaust valves on each cylinder. The cylinders and crankcase are integrally cast, forming a rigid unit. The fully balanced crankshaft is supported by four, unusually large, main bearings. The head employs a cross-flow design with hemispherical combustion chambers.

6-232, 6-258

The AMC-built inline 6-cylinder engines are of conventional overhead valve configuration and cast iron construction, and are virtually identical in design. Engines built through 1972 use rocker arms mounted individually, while 1973 and later engines mount the rocker arms on a common shaft. The crankshaft is supported by four main bearings.

8-304, 8-327, 8-360, 8-401

These AMC-built, 90º V engines are of the overhead valve configuration and cast iron construction. The rocker arms are individually mounted. On the 360 and 401, the exhaust valves are equipped with rotators. The crankshaft is supported by five main bearings.
